LG split system heater cooler. the heater is not working and fan outside is working

CH-06 REFERS Indoor unit coil sensor fault. Disconnect from PCB measure resistance. 10 kOhm at 10C and 4 kOhm at 30C. if not replace sensor. THANKS.

yes i would change the fan motor . and the capacitor

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.

a split system can be gas or can be a heatpump. a split system is when the condenser coil compressor and outdoor fan is outside. the other half is in the house close to your air filter .that well be your air handler. eletric heater. or gas burner .and indoor fan motor would be. i hope that helps you.

check the compressor's start/run capacitor. if it is swelled at the top, where the connectors are, replace it.

Wash out your outside coil and monitor the outside fan. sounds like a lockout due to dirty condenser or intermittent motor operation. Could mean condencer air problem.

This could be a problem with the interconnecting wiring or a control board problem with either the indoor or outdoor unit. I would have these issues looked out.
Hope this helps

if the cooling is ok then the reversing valve outside may be faulty

air conditioner can work at 0 deg C outside temp and you do not need a heater for compressor if is split system.

Solution # 1, Check Condensor Fan Motor Capacitor 4uf or MFD
# 2, Check Motor Windings
# 3, Check Relay OR Defination Contactor
# 4, Check Connection Terminals

hope will help u 2 solve this

GOOD LUCK
